 Some differences from the "normal function" version:
 
-- It provides typechecking and autocomplete for static properties like `displayName`, `propTypes`, and `defaultProps` - **However**, there are currently known issues using `defaultProps` with `React.FunctionComponent`. See [this issue for details](https://github.com/typescript-cheatsheets/react-typescript-cheatsheet/issues/87) - scroll down to our `defaultProps` section for typing recommendations there.
+- `React.FunctionComponent` is explicit about the return type, while the normal function version is implicit (or else needs additional annotation).

-In most cases it makes very little difference which syntax is used, but the `React.FC` syntax is slightly more verbose without providing clear advantage, so precedence was given to the "normal function" syntax.
